You can establish a cluster in two ways: manually and automatically. With the latter, you can establish a
cluster according to the prompt information. The system:
1) Prompts you to enter a name for the cluster you want to establish;
2) Lists all the candidate devices within your predefined hop count;
3) Starts to automatically add them to the cluster.
You can press Ctrl+C anytime during the adding process to exit the cluster auto-establishment process.
However, this will only stop adding new devices into the cluster, and devices already added into the
cluster are not removed.
Follow these steps to manually establish a cluster:

Configuring Communication Between the Management Device and the Member
Devices Within a Cluster
In a cluster, the management device and member devices communicate by sending handshake
packets to maintain connection between them. You can configure interval of sending handshake
packets and the holdtime of a device on the management device. This configuration applies to all
member devices within the cluster. For a member device in Connect state:
z
If the management device does not receive handshake packets from a member device within the
holdtime, it changes the state of the member device to Disconnect. When the communication is
recovered, the member device needs to be re-added to the cluster (this process is automatically
performed).
z
If the management device receives handshake packets from the member device within the
holdtime, the state of the member device remains Active.
Follow these steps to configure communication between the management device and the member
devices within a cluster:
